To all whom 'it may concern:

Beit known thatwe, EDVARD ELLEFsnN and Louis LAMBIN, itizens of theUnited States, and residents of Chicago, in the county of Cook and Stateof Illinois, have in,- vented certain new and useful Improvements inCan-Making Machines, of which the following is a speciication.

This invention rela-tes more particularly 0 to a machine which is adated to force the two ends of a can onto the ody thereof and also to Crimthe ends or heads after they have been forced in position. The latteroperation is desirable .for closing the ends 5 tightly upon the canbodies.

i y means of this invention, a novel and eflicient can-header .isprovided and also means whereby the cans are crimped before they aredischarged from the machine. lts objects are to provide suitablemechanism to ere-tions, such mechanism to be of as simp e constructionas possible, consistent with the work to be performed.

ln the accompanying drawings illustrating this invention, Figure 1 is anend view of the machine which is designed for vc individual heading andcrimping' mechanisms, but for convenience in illustration only one ofsuch mechanisms is shown. Fig. 2 is a partial front view of the machine,butin this view as in the subsequent views, parts are broken away, shownin section, or omitted n order to make the mechanism more readilyunderstood. Fig. 3 is a top plan view of a inachine. Fig. 4 is asectional view taken on the line 2l, 4f. of Fig. 2 looking in thedirection of the arrows. Fig. 5 is a detail showing one of the grippingdevices detached, together with a can and the heads in position forheading. Fig. 6 is a view similar to Fig. 5 showing the part-sin theirrelative positions after the jaws Vare closed and the can headed. Fig.'7 is an end view showing the gripping jaws open, and Fig. 8 is a detailshowing thc rotating spindle engaging with a headed can, the crimpingwheel being indicated in dotted lines, and fragments of the open jawsbeing shown in section.

The mechanism will be more readily un- O/derstood if the sequence of theoperations, which are as follows, are kept in mind. The bodies and headsare fed into the machine, either simultaneously, or the bodies slightlyin advance of the heads as is shown at U, O. The upper grip icrs areforced in and down to coact with t e lower'saddles to hold the to lochthe sa ldles in position. The spindles with their ends for engaging theheads are next forced in and carry with. them the slides carrying thegrippers to force the heads on I bodies a nd heads in proper positionand also l the bodies.

l The spindles and slides being i held in this position, longitudinali;the upl per jaw is thrown up and out to release the i can andsimultaneously the .lower jaw is swung in and down, the headed can nowheing supported between the constantly rev olv- The crim )ing wheelsnext move toward the can and engage the heads to perform the crimpingoperation. As this is completed; the can is thrown out, the sad dlesagain assume their normal positions and are ready to rcccive anotherbody and heads.

ing spindles.

a. A pair offdisks or wheels B, l5 are rign idly mounted On the mainshaft and are provided with one or more slideways b, in this instancetive, for the slides C which carry the can gripping and headingmechanism. It is of course understood that the slideways are inalinenient, so that corresponding heading n'iechanisms will coact toforce the heads on the bodies received in oppositely disposed. gri pers.Each of the slides C is provided Wit 1 bearings c, c', for arevoluble'spinille c2 which is provided with an enlarged end o;z whichis rcferably beveled to engage1 with the slight y recessed can head asshown in Figs. 5 to b. Each of the spindles c2 may be revolved :it anydesired speed by iucans'of gears o which mesh with large. gears o'Lwhich are loosely mounted on the [nain shaft a'. The gears c4 are drivenby means of pulleys ci and belts c from. any convenient source of power.By means of this arrangement the live spindles at each end of themachine aro, all driven inde )endcntly of the speed of the main shaft.he ears cS arc made with a suflicient face to al ow for a slightlongitudinalniovenient of the s indlcs without being thrown out of gearwitll the large gears c.

The spindles cL are provided with sleeves loosely ino unted thereon and.having arms or lugs d extending to one side. The latter are bored toengage with uide rods d" secured in bearings d, da Whici are riffidlyconnected with the bearings c, c. Col ars (Z4, di are rigidly secured tothe spindles c2 and turned therewith. These collars are adapted toengage at times respectively with the inner i The frame il is providedwith suitable i lijf) pivoted to lugs b on the disks B, B. opposite endsof secured to the rings F, F

faces of the bearingsq'c, of the slides C. In order to reciprocate thelatter' a spring d is inteosed between the sleeve D and the E collar 5in order to give a resilient pressure to the slide when it 1s moved 1nto head the can. There 1s a slight play between the collars d4, d5 andthe bearings r, c to allow for i the forward movement of the spindle inorder that its end c3 may enter the recess in the can head before theslide moves forward to perform the heading operation. The outer ends ofthe arms d engage with levers E which YIarle e the levers E are providedwith rollers e which engage with cam tracks F2 which are adaptedmovement to the levers E in order to reciprocate the sleeves l) to movethe spindles and the heads'. The cam tracks F2 are preferably formed bymeans of rings F, F which are rigidly secured by means of lugsf to theframe A and are provided with annular cam strips f', which are beveledas shown in Fig. 3 to throw the rollers e out at the proper time. Thecorresponding cam rings f2 are in order to hold the rollers e inengagement with the faces of the cam stripsf to give the properreciprocating movement tothe levers E.

Each of the slides C is provided with a saddie G. which is pivoted at gto lugs c7 on said slides. The saddles are provided with inwardlyprojecting arms g which are adapted to engage with suitable cani stripsH to throw the saddles in toward the center and away from the headedcans. Springs g2 are interposed between the arms g and the ends of theslides Cin order to hold the saddles in normal position. The cam stripsH are secured by means of slotted arms h and set 'screws or the like 7Lto a disk or ring which n surrounds the main shaft at substantially thecenter of the machine and is fastened by i2 to the frame A.

means of an arm i and lug The clamping jaws `J are carried on sleeveswhich are supported and slide on rods jg rigidly secured in bearin s jaon the slides C. The rods j? are shouldered at jt 'to form bearings forsprings ji which bear at vtheir op osite'lends with the inturnediiangesof the s eeves in order to hold. said sleeves, together with theclampinOr jaws, in` normally retracted osition. vigidly secured to eachof the sieeves j is a cam piece j which is adapted to engage with aprojecting cam]3 on the inner side of the ring F to urge said sleeveforward to bring the jaw J in proper osition to coact with itscorrespondm sad e G.

Vhen the can body X with the heads are r in position in the saddles asshown in Fig. 5,

and the sleeve y' (with the jawl J have been moved forward in alinementwith the corresponding saddle G, it is necessary to swin the jaw down toengage with the body an to give the lateral i l. head and to bring itslocking end gf into engagement with the correspondingly notched end gfnf the saddle. This is accom lished i by means of shoes K, shown best inig. 4, which are adapted to engage with the upper j rounded portions orprojections of the jaws J. The shoes are provided with tongues r whichengage with slideways inbrackets 7c mounted on the rings F, F. Springsk2 inter )osed between the ends of thel tongues L', an( the upper partsof the brackets /c provide for a yielding engagement between the l shoes.li and the jaws. The shoes are prel vented from being disengaged fromthe I 3 provided with g brackets by means of rods stops cl.

lt is only necessary to hold the jaws J t closed while the slides arebeing forced in to head the cans. The jaws are then thrown out by meansof cams or suitably shaped .I strips L which are secured to the rings F,F and engage with pins js on the jaws'J. jllllhen in the course ofrotation these pins strike the cam strips L, the jaws` J are swung outon their pivots as shown in Fig. 7 and the springs js draw the jaws backto their normal position as shown in Fig. 5.

The saddles G being swung out b the cams H, and the jaws being drawnback, the headed cans are supported between the revolving spindles 02 asindicated in Fig. 8, and the can is ready to be crimped. This is done bymeans of crimping wheels M which are revolubly mounted on adjustablearms m carried by short rods my', having bearings in the disks B, B andalso in auxiliary disks M, M2, mountedon the main shaft al on eitherside of the ring T. These shafts are turned at the proper time -to bringthe wheels in engagement with the can ends by means of crank arms m2rigidly secured to the inner ends of said shafts. These arms areprovided with cam rollers m3 which are adapted to engage with cam slotsfm in the faces of stationary disks M3 rigidly secured to the ring I orintegral therewith. The cam slots m3 are so designed that the crimpingwheels M will be thrown into engagement with the can heads immediatelyafter the heads have been forced ontothe bodies and the jaws released.The cans being rapidly rotated by means of the gearing heretoforedescribed, the pressure of the crimpinfy wheels will cause the heads tobe crimped in the manner desired.

As soon as this 1s accomplished the completed cans are discharged at thelower side of the machine, and toy insurethc proper discharge, a resililent finger N is secured to the lower side ofA the ring l and projectsdownwardly into the Y ath of the rotating cans. The cam tracks aredesigned to release said cans and to return so that the rollers e willbel thrown in toward the rings F, F', at the time. when the cans are tobe discharged in orderi the slides i `and adapted to outer can and.can-head engaging iaws also 4adapted to receive and position to receiveother' bodies `What We claim and desire to secure by Letters Patent is:l
